I like the story, and although Web 3.0 has great potential, I believe it has three key issues to address.

First is to gain widespread adoption when centralised Web 2.0 makes everything so deceptively easy for non-technical (and non-aware) users.

Second is to mitigate the way people will generally act and vote) for their own short-term gain and interest, or just generally do dumb things because they don't understand or are outright malicious. (to paraphrase George Carlin “Think of how stupid the average voter is, and realize half of them are stupider than that.”)

Finally, and possibly the hardest one, is that Web 3.0 "communities" by their nature are decentralised. Centralised governments have a relative monopoly on the use of violence, and will happily exercise it if they feel threatened. How do decentralised, often distributed, communities defend themselves against organised groups of men in uniform with guns ?
